Unlike most reviewers here, I am not using this NAS to stream movies, I am an IT pro that is using this in a small enterprise to host VMware virtual servers. A total of 4 VMs are hosted on the array. My configuration is 4x 2TB WD RE drives in a RAID 10 iSCSI SAN. I have configured all 4 NIC ports in aggregate on a Gigabit Switch. The VMs I am using do require quite a bit of disk I/O (Exchange,Terminal,File Servers). This NAS has exceeded my expectations. I haven't come close to experiencing a bottleneck due to this configuration. From the network, memory, and CPU, I feel even with the taxing setup I've thrown at it, it hasn't broken a sweat. I wish that this model were available in a rack mountable configuration, however from a performance perspective this thing has been a champ. I highly recommend if you are purchasing this for a small virtual environment such as this.
Maybe the most powerful 2-bay NAS on the market. But it is not very cool to know that QNAP remove flexible volume from x53 PRO series. Stupid marketing thing, you know, not due to hardware limitation but product positioning...[UPDATE: They now add this feature back.] Anyway, compared with another great NAS productor Synology, QNAP is: Pro: 1. More stable, less likely to lose data or mess things up. (All QNAP x86 NAS models have a internal storage to keep a copy of the operate system, even all your disks get messed up somehow will not prevent your unit from booting up again, and it is good for other security reasons, for example it can prevent malware since a copy of the OS is protected inside the internal storage, no way to access without opening the case of NAS. Meanwhile all Synology NAS keep multiply copies of the system on the drives you plug in, space consuming and still can be damaged physically or by malware.) 2. Better specifications for same amount of...
So far this NAS is great. I've had it 2 weeks now, so not a lot of run time yet, but setup was super easy, it took about 10 mins to install 4 4TB Seagate NAS drives (ST4000VN000). There have been 2 firmware updates already, so there are probably some stability issues lurking with the original software, but I haven't experienced them yet. I'm replacing an old ReadyNAS NV+ and the speed difference is night and day! Directories load very quickly (using a single GE link right now and connecting through wireless at 150Mbps (2 MIMO) speeds at the laptop. I've setup a Time Machine partition and have 2 MAc laptopns (OS X 10.9.5) backing up to it. I also had the ReadyNAS push the directories of 60K+ pictures and 900MBs of music over without any problems, although it took a long time to complete.
In terms of noise, it's very quiet. I haven't measured the DBs but the fans are spinning at low speed, around 400 RPMs and the drives are very quiet too. My only complaint is that with the...
